MicroStrategy fell as much as 18% on Tuesday

Meanwhile, bitcoin fell on Tuesday, sliding below $63,000 at one point, about $10,000 below last week’s record high. MicroStrategy tends to trade in tandem with cryptocurrency.

Key catalysts such as spot bitcoin exchange-traded funds and April’s upcoming “halving” event — which cuts the reward for mining bitcoin in half to limit supply — have helped buoy the leading crypto and stocks tied to its performance.

MicroStrategy started out as an enterprise software provider, but began using an aggressive Bitcoin buying strategy in 2020 and has since then primarily traded as a crypto price proxy. This February, the company said it would shift its focus and brand to bitcoin development.

MicroStrategy shares are already up 124% this year, compared to Bitcoin’s 50% rise. Both started to slide last week as investors took profits.
